The formulator or compounder will need to add nucleating agents, impact modifiers, reinforcing agents, etc. to meet the requirements of their application. 2500HP biopolymer can be processed on most conventional extrusion equipment. The material is stable in the molten state, provided that the drying procedures are followed. The resin should not be exposed to atmospheric conditions after drying. Keep the package sealed until ready to use and promptly reseal any unused material. Pellets that have been exposed to the atmosphere for extended time periods will require additional drying time. Amorphous regrind must be crystallized prior to drying, to assure efficient and effective drying. Startup and Shutdown Process details: 1. 2500HP is not compatible with a wide variety of resins and special purging sequences should be followed: 2. Clean extruder and bring temperatures to steady state with low-viscosity, general-purpose polystyrene or polypropylene. 3. Vacuum out hopper system to avoid contamination. 4. Introduce Ingeo polymer into the extruder at the operating conditions used in Step 1. 5. Once Ingeo polymer has purged, reduce barrel temperatures to desired set points. 6. At shutdown, purge machine with high-viscosity polystyrene or polypropylene.
